Report: Seahawks' Portis arrested on suspicion of DUI

Seahawks backup quarterback Josh Portis was arrested earlier this month in Seattle on suspicion of DUI, Bob Condotta of The Seattle Times reports.

According to Condotta, Portis was will be arraigned on May 28 for the May 5 arrest in which he allegedly registered blood-alcohol levels of .092 and .078 after he was pulled over for speeding on eastbound 1-90. The state's legal limit is .08.

Portis, 25, is one of three Seahawks quarterbacks vying for a backup role behind starter Russell Wilson.

Portis was signed as an undrafted free agent out of California University in Pennsylvania in 2011 and spent his rookie season as Seattle's third quarterback. He spent 12 weeks on the practice squad last year before he was released in November, and he signed a two-year deal last month.
